Abstract

Multilayer structures of ZrB₂ containing 30-70 wt% Ti were fabricated using a laser sintering/melting technique. Ti acted as the binding interface for the hard ZrB₂ particles. Structural properties and oxidation behavior of laser-sintered samples were studied using high-temperature X-ray diffraction (HTXRD). HTXRD revealed the formation of boride solid solutions (Zr_0.61Ti_0.39B₂, Zr _0.2Ti_0.8B₂), Zr_0.3Ti_0.7 and TiB whiskers as well as several oxide species (Ti₂ZrO and ZrO_x) during laser sintering process. Laser-sintered Ti-ZrB ₂ mixtures had high relative densities (>92%) and hardness values (up to 11.4 GPa). The reactions enhanced dissolution of ZrB₂ into Ti, governing the final compositions of the mixtures and facilitating the production of high-density boride solid solutions.
